However, it's important to notice that MEI makes a distinction here: in data.duration.mensural, there is a \"longa\" value, while data.duration.cmn has a \"long\"; the same applies to \"brevis\" and \"breve\". They do look the same, but they shouldn't be used across repertoire boundaries – why would MEI make this distinction if not for this very purpose?\r\n\r\nYes, probably useful to have separate namespaces for CMN and Mensural note names -- although longs and longas will have very similar graphical syntaxes since longs are analeptic in modern notation.\r\n"}}
